Abstract: The historical development of steam boiler technology aboard steam- and later motor-ships is reviewed, setting the stage for statistical investigations of langer term trends in the frequency of boiler explosions. Two different measures of the safety performance have to beaddressed in such an analysis: The explosion rate per ship- or boiler-year in an entire fleet, and the failure ratio, i.e. the probability that a boiler of a certain vintage suffers an explosion during his useful life. The major obstacle for both analyses, the distortions due tostatistical fluctuations, have been dealt with by applying a special smoothing procedure. The failure ratio analysis requires further an estimation of failures to be statistically expected in the future; this is accomplished by means of a previously developed methodology. This paper is primarily concerned with the statistical analysis of boiler exolosion data. The methodology is published elsewhere.
